What if my girlfriend wants to travel abroad and can't come up with so much money at once?

If your girlfriend wants to travel abroad, you can't afford a lot of money at once. At this time, the best way is to do more part-time jobs. Or you can borrow some from friends with better economic conditions around you, or you can use Alipay's ant flowers. If it really doesn't work, explain the situation to your girlfriend. She is your girlfriend. She loves you, so she should forgive you.
